hi, my name is tom. i have md,diagnosed in 04,i was putting up with pain(high tolerance for pain),but it became too much,asked neurologist what i could do? was walking with pain like cripple. could not get comfortable in bed till i found the right position where leg did not hurt. dr prescribed acordia and i took my first pill yesterday at 4 pm and when i awoke this morn at 5am-no pain. my wife said it's too premature to claim it is the pill,but, i am hopefull. it is 10mg twice a day,i didn't want any more meds,but this sure helped. drove for about 3 hrs today and normally left leg at ankle would be extremely painful. podiatrist diagnosed it as mid foot arthritis,i am 59. did not know arthritis would be that painful. now i am not sure if it's the ms or arthritis. leaning toward ms pain,hope this info helps and gives new hope to pain sufferers.
